`ts
import { Volume } from '@jsonjoy.com/fs-node';

const vol = new Volume();
vol.writeFileSync('/hello.txt', 'Hello, World!');
console.log(vol.readFileSync('/hello.txt', 'utf8')); // Hello, World!
`

$3

`ts
import { Volume } from '@jsonjoy.com/fs-node';

const vol = Volume.fromJSON({
'/app/index.js': 'console.log("Hello");',
'/app/package.json': '{"name": "app"}',
});

console.log(vol.readdirSync('/app')); // ['index.js', 'package.json']
`

API

The Volume class implements Node.js fs module's synchronous and callback APIs:

- readFile, readFileSync
- writeFile, writeFileSync
- mkdir, mkdirSync
- readdir, readdirSync
- stat, statSync
- unlink, unlinkSync
- ... and many more

It also exposes a promises property for the Promise-based API:

`ts
const data = await vol.promises.readFile('/hello.txt', 'utf8');
